These are the last gel I take in a long run to get me over the tough home stage. The lift is actually obvious, you feel so much better and it gives you the energy and will to finish. Taste isn't too bad either, it's a sort of combination of berry with burnt coffee (but better than I make it sound).

Core Gel
Go down with no issues, taste is inoffensive and they give the required boost. Only small issue is they can be a little fiddly to open and you end up getting sticky gel on your hands that you have to deal with for the rest of your run

Great product- good price
These are invariably expensive in the supermarkets or they never have the right flavour etc etc. However good price, right flavour, all good!

Great
I used these for running & the gym. I don't drink caffeine so these give me a boost.

Another effective product from SIS.
Like the other SIS products we've used the Caffeine gel worked as expected, on a personal note my son (who I buy these for) didn't like the taste. But the taste is secondary to the performance of the product which is excellent.

Some missing from the box.
This is not a review of the product, but my overall experience. Outer plastic packaging was complete, but the bottom of the box had clearly been opened and two gels were missing. Too much trouble to return it because of this, but really annoying that this has happened.

Pretty horrible taste when you need it least
Pretty horrible taste when you need it least. Not as easy on the stomach as the SIS isotonic gels. Not sure where the caffeine becomes a benefit in endurance sport, but that's just my limited experience. Try a single one before paying out for a box.

He consumido muchas marcas de geles energéticos y estos se digieren muy fáciles y son agradables para consumir. Hay otros que hostigan y son difíciles de tragar. Estos son muy líquidos y con balance perfecto de azúcar. He consumido 4 y hasta 5 en una media maratón sin ningún trastorno de estómago. No necesitan agua para consumirse

Das Science in Sport Go Energy plus Koffein Gel ist eine durchwachsene Erfahrung, die sowohl positive als auch negative Aspekte aufweist. Hier sind meine Eindrücke: Einer der positiven Aspekte dieses Gels ist der Geschmack. Es ist in verschiedenen Geschmacksrichtungen erhältlich und bietet eine angenehme Abwechslung für Sportler. Der Geschmack ist nicht überwältigend süß, was während des Trainings angenehm ist. Die Kombination aus Energie und Koffein kann in bestimmten Situationen vorteilhaft sein. Der Energieschub, den das Gel bietet, kann dazu beitragen, die Leistung während intensiver Trainingseinheiten oder Wettkämpfe zu steigern. Allerdings kann der hohe Koffeingehalt auch negativ sein. Manche Menschen reagieren empfindlich auf Koffein und könnten unter Nebenwirkungen wie Herzrasen oder Nervosität leiden. Es ist wichtig, die persönliche Toleranz gegenüber Koffein zu berücksichtigen. Die Konsistenz des Gels ist relativ dick, was das Schlucken während des Trainings erschweren kann. Einige Sportler bevorzugen dünnflüssigere Gels, die sich leichter einnehmen lassen. Insgesamt hängt die Wirkung und die Zufriedenheit mit dem Science in Sport Go Energy plus Koffein Gel von den individuellen Vorlieben und Toleranzen ab. Es kann in bestimmten Situationen nützlich sein, sollte jedoch mit Vorsicht verwendet werden, insbesondere wenn es um den hohen Koffeingehalt geht.
